The location services facility may provide theaggregate data 102, in raw or processed forms, to a third-party serviceprovider 200. In some embodiments, the present invention may comprise anetwork 304, which in some embodiments may be a peer-to-peer (P2P)network, comprising a plurality of facilities wherein each of theplurality of facilities may be a portable electronic facility 300 acrosswhich may be distributed the database 100, or its equivalent orconstituent components 302, containing, in whole or in part, theaggregate data 102. An expanded view of one aspect of the P2P network isshown in FIG. 3. These embodiments are discussed in detail below andother embodiments will be apparent from the following discussion.

Referring to FIG. 4, the disclosed invention may gather a datum 104 froma portable electronic facility 300. The datum 104 may be stored in thedatabase 100. In particular, the datum 104 may be representative of aposition and/or velocity associated with the portable electronicfacility 300. Alternatively or additionally, the datum may berepresentative of an output value from a sensor associated with theportable electronic facility 300. In most cases, an additional datum 104from the portable electronic facility 300 or another portable electronicfacility 300 may also be stored in the database. The aggregate of aplurality of datum 104 from one or more portable electronic facilities300 may comprise aggregate data 102, which may be stored within thedatabase 100.

Referring again to FIG. 1, the aggregate data 102 may flow from thedatabase 100 to the application server 108. The application server 108,in turn, may provide an application based service, a number of which aredescribed below and the general provision of which further comprise thedisclosed invention. The application based service may be provided to auser of the portable electronic facility via a Web interface such as aWeb browser. In this case, embodiments may comprise the Web server 110for delivering the service.

Referring to FIG. 2, the aggregate data 102, in whole or in part, may beprovided to a third-party service provider 200 in a predeterminedformat, which may be specified by an XML schema. As provided, the datamay be formatted or modified according to various needs, includingwithout limitation a need of a first end user 202 who may be a dataconsumer (such as, revealing consumer behavior); a need of a second enduser 204 who may be a user of the portable electronic facility (such as,obeying a privacy agreement associated with the data); and/or a need ofthe third-party service provider 200 (such as, receiving data in a filethat is formatted to facilitate automated processing). When formatted,the data may comprise a report, which may be a computer generatedreport.

The third-party service provider 200 may in turn provide a service tothe first end user 202 or the second end user 204, wherein the servicemay be associated with the data. In some cases, the first end user 202may be a marketing organization. Other cases will be apparent due to thefollowing description.

In one embodiment, the aggregate data 102 may be disaggregated andprovided to the third-party service provider as a single data point.This may be useful in many applications including, but not limited to, aservice that provides to the end user a map showing the location of theuser and the user's immediate surroundings; a service that provides tothe end user a map showing the location of a point of interest in thevicinity of the user; a service that provides to the end user a mapshowing the location of another user; a service that provides to the enduser a map showing the location of a pet associated with the user,wherein the pet may be fitted with a collar containing a portableelectronic facility; the establishment of a geofence (described below indetail) and the monitoring of the portable electronic facility withrespect to its crossing the geofence; and so forth.

In another embodiment, the aggregate data 102 may be scrubbed andprovided to the third-party service provider 200 as a generalizeddataset. This may be useful in many applications including, but notlimited to, a service that may provide to a marketing companydemographic information that may be representative of the generalizeddataset, which may be representative of a plurality of users in a givengeographical area; a service that may provide the user with highwaytraffic information that may be based upon aggregate traffic flows,which may comprise the generalized dataset; and so forth. For exampleand without limitation, in one application, the generalized dataset,which may comprise demographic information, may be representative ofusers' gender and spending habits, wherein the spending habits comprisethe means and routes utilized by the users to arrive at a shoppingdestination. The generalized dataset may further comprise a uniqueidentifier associated with each user represented, wherein the uniqueidentifier may obscure the identity of each user while also allowing thethird-party service provider 200 to discriminate between users,especially during an analysis of the generalized dataset.

In yet another embodiment, the aggregate data 102 may be provided in itsentirety to the third-party service provider 200 as a comprehensivedataset. This may by useful in many applications including, but notlimited to, a service that may provide to a logistics company detailedtracking information pertaining to a fleet of delivery vehicles, whereineach vehicle is located and tracked through time; a service that showsto a head of a household a plurality of locations representative of eachof the members of the household; and so forth. For example and withoutlimitation, a company providing cleaning services may utilize theaggregate data 102 to track how long its employees dwell at eachcustomer location and which routes the employees take to travel to eachcustomer location. This information may be useful in monitoring theefficiency of its employees and in optimizing assignments given toemployees, for example and without limitation, by grouping jobs given toa particular employee into a smaller geographical area.

In still yet another embodiment, the aggregate data 102 may be processedto provide a service to a plurality of users. One example is a socialnetworking application. For example, without limitation, a datingservice may allow the plurality of users to enter individual preferenceinformation associated with a desired characteristic of a mate.Processing of the aggregate data 102 may allow the service to recognizewhen pairs of mutually desirable mates are in close proximity of eachother. Data associated with this recognition may be transmitted to oneor both users in the pair, allowing the users in the pair to meet eachother. This transmission of data may be in the form of an alert, such asa text message, e-mail, automated telephone call, and so forth. Foranother example, an interested-based social network application mayallow the plurality of users to enter individual preference informationassociated with a favorite pastime, such wine tasting. Processing of theaggregate data 102 may allow the service to recognize when eventsassociated with the favorite pastime are being held in proximity to theusers. Relevant users may be notified and additional information, whichmay encourage social interaction between the users, may be provided tousers on the basis of the contents of the aggregate data 102. Forexample, a subset of users may, based upon observed travel patterns inthe aggregate data 102, be likely carpool candidates to a local winetasting event.

Generally, in embodiments, the aggregate data 102 may be disaggregated,scrubbed, reformatted, transmitted as-is, stored, processed, and/orformatted in any practicable manner that is useful to any particularthird-party application. Moreover, in embodiments, an alert may betransmitted to a user, wherein the alert comprises data that isassociated with a recognition that is associated with some form orcomponent of the aggregate data.

Referring now to FIG. 5, in one aspect, a system according to thepresent invention may comprise a database server 500, which may comprisethe database 100; a Web/Application server 502, which may comprise theapplication server 108 and the Web server 110; and a storage device 504,which may store the database 100.

The database server 500 may also store information pertaining to theuser's privacy or security. The user may be provided an option to chooseif the location and/or velocity of the portable electronic facilityassociated with the user is recorded in the database 100. This enablesprivacy by allowing the user to determine the persistence of dataassociated with the user. The user may also be asked to provide apersonal identification number (PIN), which may be entered into ahandset that may be the portable electronic facility 300. This PIN,perhaps in conjunction with the handset's phone number, comprises anauthentication code needed to access a service enabled by the presentinvention, for example and without limitation, a Web site that providesa map showing the location of the user.

The database server 500 may also store information pertaining to theuser's level of access to a service enabled by the present invention.This access level may be used to determine a user's privileges. In oneinstance, a parent may want to allow a child to have access to thelocation of other family members, but not allow the child to establish ageofence (described below) or an alert. In another instance, a pluralityof handsets may be configured as peers in the network 304 when thenetwork 304 is embodied as a P2P network. In this embodiment of thenetwork 304, a first peer may exchange location and/or velocity datawith a second peer provided that the second peer has an appropriatelevel of access to such information from the first peer. In yet anotherinstance, the exchange of information from the first peer to the secondpeer may be conditioned on the second peer having both the appropriatelevel of access and the user of the second peer providing a PIN and/orauthentication code that corresponds to a code stored in the database100.

In other embodiments, some or all of the information pertaining to theuser's level of access to a service is stored in the distributeddatabase component 302 associated with the portable electronic facility300.

In the portable electronic facility 300, it istypical for the power consumption to be dominated by RF transmissionelectronics that may be integral to the facility 300 and of which thedata communication facility 610 may be comprised. This is due totheoretical and practical limitations of the physics of RF transmission.The battery life of the portable electronic facility 300, then, may beimproved by limiting the amount of time that the portable electronicfacility 300 is transmitting data: the transmission electronics may bepowered down the rest of the time. Likewise, it is known that the powerconsumption of RF receive electronics, of which the data communicationfacility 610 may also be comprised, may have a considerable impact onthe battery life of the portable electronic facility 300. It followsthat methods for limiting the amount of time that the portableelectronic facility 300 is sending and/or receiving data may be presentin some embodiments of the location services facility. These methods maycomprise varying the length and/or frequency of transmissions to and/orfrom the portable electronic facility 300.

Another consideration in the design of the portable electronic facility300 may be a speed with which the facility provides the user with dataand/or the accuracy of the data. In embodiments, the portable electronicfacility 300 and/or the location services facility at large may bedesigned to vary the length and/or frequency of data transmissions toand/or from the electronic facility 300 to improve the speed with whichthe facility 300 provides a user with data and/or the accuracy of thedata.

One aspect of the location services facility is to provide locationinformation to the user. Location information may comprise latitude;longitude; altitude; depth; pitch; roll; yaw; time; velocity; ororientation and/or distance to or from a waypoint, an origin, adestination, magnetic north, or true north. The location may bepresented to a user in a number of embodiments including, withoutlimitation, a map, a moving map, an interactive map, a textualdescription, a spoken description, a color code, an aural code, ane-mail, a text message, a pager message, a printout, and so forth.

The location information provided by the location services facility tothe user may originate from the use of various methods incorporatingdata from a sensor facility such as, without limitation, a globalpositioning system (GPS), a radio frequency identification (RFID), aplurality of cell phone towers (for example, for time and/ortriangulation), an altimeter, a depth gauge, a gyroscope (including“gyroscopes” that use a vibrating structure, a laser, or a MEMS device),an inertial sensor, a compass, an accelerometer, a speedometer, aseismometer, a magnetometer, a thermometer, a photon detector(including, but not limited to, a visible camera, an infrared (IR)detector, an ultraviolet (UV) detector, an X-ray detector, a gamma-raydetector, a Geiger counter), a hygrometer, a heart rate monitor, a bloodglucose meter, a blood oxygen meter, an electrical sensor, an electricalinterference sensor, a current sensor, a resistance sensor, athermistor, an electrostatic sensor, a frequency sensor, a temperaturesensor, a heat sensor, a thermostat, a differential light sensor, anopacity sensor, a scattering sensor, a diffraction sensor, a refractionsensor, a reflection sensor, a polarization sensor, a phase sensor, aflorescence sensor, a phosphorescence sensor, an optical activitysensor, an optical sensory array, an imaging sensor, a calibrated micromirror array, a calibrated pixel array, a micro mirror array, a pixelarray, an angular momentum sensor, a rotation sensor, a rotation speedsensor, a rotation direction sensor, a velocity sensor, an inclinometer,a momentum sensor, a smoke detector, a fire sensor, a heat detector, acombined heat and smoke detector, a vapor sensor, a gas sensor, a signalsensor, a wireless signal sensor, a cellular signal sensor, a Wi-Fisignal sensor, an Internet signal sensor, a touch sensor, a contactsensor, a viscosity sensor, a position sensor, a height sensor, a raydetector, a microwave sensor, a proximity sensor, a distance sensor, amotion sensor, a range sensor, a mote, a marker, a powered marked, asignal emitter, a signal receiver, a powered signal emitter, a poweredsignal receiver, a chemical sensor, a fire sensor, a hazardous materialsensor, a hazardous vapor sensor, a biohazard sensor, a bacteria sensor,a virus sensor, an anthrax detector, a nerve gas sensor, a poisonous gassensor, a carbon monoxide detector, an energy sensor, or an aerosolsensor. RFID tracking may, without limitation, comprise a portableelectronic facility further comprising a RFID transponder that isinterrogated by electronic equipment that is installed along a roadway,along a sidewalk, at the entrance of a building, at the egress of abuilding, or in a building. Once created, the location information maybe compiled, accessed, processed, searched, sorted, or in any other waymanipulated for the benefit of the first end user 202, the second enduser 204, or any other entity that values the user's locationinformation. In embodiments a location may be obtained from a database,such as based on the location of a wireless access facility, such as aWi-Fi or 802.xx access point, switch, or similar device.

In embodiments, an individual location information sample, which may bea datum 104, may be subject to errors, which may be due to physical orpractical limitations of the location services facility. For example,cell phone triangulation systems are limited by RF multipath effects dueto large metal structures such as building or water towers. One methodof compensating for these errors may comprise processing multiplelocation samples to determine, via statistics or heuristics, to whatextent the individual location information sample may be reliable.Another method of compensating for these errors may comprise processingmultiple location samples to determine an aggregate location informationsample that may include information such as mean location and standarddeviation, which may provide a more accurate determination of locationthan the individual location information sample.

Referring now to FIG. 7, the portable electronic facility 300 maycomprise a state machine 702 heuristic approach to obtaining a GPS fix700. The state machine 702 may comprise a plurality of states, 704, 708,710, 712, 714, and 718. The state machine 702 may comprise a fix delay,which may be a string that may be processed by the central processingunit 612, the operating system 614, the software application 618, thegeolocation facility 620, or any other facility associated with thegeolocation facility 620. In the plurality of states,“mposition:delay=low” may indicate a fix delay that may take no greaterthan 32 seconds to provide a limited degree of computation fordetermining a low-accuracy velocity of the portable electronic facility300. “mposition:delay=high” may indicate a fix delay that will take nogreater than 3 minutes and 32 seconds to provide a substantial degree ofcomputation for determining a high-accuracy velocity of the portableelectronic facility 300.

The Inside State 704 may reflect that the facility 300 may be receivingthe GPS fix 700 from a tower. In this state, the facility 300 may sleepfor 90 seconds and then may attempt to receive a fix, at first, usingmposition:delay=low and then for every fix thereafter usingmposition:delay=high. Should the facility 300 receive five fix attemptsin the Inside State 704, the facility 300 may go into the Sleep State704.

The Stopped State 710 may reflect that the facility 300 may be receivingthe GPS fix 700 from a satellite and that the facility 300 may beassociated with a speed, according to the fix's National MarineElectronics Association's (NMEA) string 720, of approximately 0kilometers per hour (KPH). In this state, the facility 300 may sleep forapproximately 90 seconds and then may attempt to receive a fix usingmposition:delay=high. Should the facility 300 receive five sequentialGPS fixes 700 in the Stopped State 710, the device may go into the SleepState 704. In the Stopped State 710, the facility 300 may send every GPSfix 700, of which a datum 104 may be comprised, to a datum receivingfacility, which may, without limitation, comprise the database 100, theapplication server 108, the Web server 110, another portable electronicfacility 300 such as via the P2P network 304, or any other facilityassociated with the database 100 or the distributed database component302.

The Moving_Slow State 712 may reflect that the facility 300 may bereceiving the GPS fix 700 from a satellite and may be associated with aspeed, according to the fix's NMEA string 720, of greater thanapproximately 0 KPH and less than approximately 17 KPH. In this state,the facility 300 may sleep for 60 seconds and then may attempt toreceive the GPS fix 700 using a mposition:delay=high and every GPS fixmay be sent to the datum receiving facility.

The Moving_Med State 714 may reflect-that the facility 300 may bereceiving the GPS fix 700 from a satellite and may be associated with aspeed, according to the fix's NMEA string 720, of greater thanapproximately 17 KPH and less than approximately 106 KPH. In this state,the facility 300 may sleep for 30 seconds and then may attempt toreceive the GPS fix 700 using mposition:delay=high and every GPS fix 700may be sent to the datum receiving facility.

The Moving_Fast state 718 may reflect that the facility 300 may bereceiving the GPS fix 700 from a satellite and may be associated with aspeed, according to the fix's NMEA string 720, of greater thanapproximately 105 KPH. In this state, the facility 300 may sleep for 10seconds and then may attempt to receive a GPS fix 700 usingmposition:delay=high and every GPS fix may be sent to the datumreceiving facility.

The Sleep State 704, as is mentioned above, may reflect that thefacility 300 may have received five GPS fixes in a row in the StoppedState 710 or may have receive five GPS fixes in a row in the InsideState 708. In this state, the device may sleep for approximately twominutes and then attempt to receive a GPS fix 700 alternating with theuse of mposition:delay=high and mposition:delay=low.

The state machine may also note a significant position change wherein anew GPS fix may generate a measured change in distance of greater than10 kilometers. A check for the significant position change may be takenon every GPS fix 700 in the Sleep State 704 or Inside State 708.

When the portable electronic facility 300 is switched into anoperational mode, the facility 300 may make an attempt to retrieve a GPSfix using an mposition:delay=low. If the facility 300 cannot receive asatellite GPS fix 700 on a first fix attempt, the facility 300 mayimmediately or soon thereafter make another attempt to receive a GPS fix700 using mposition:delay=high. In either case, the facility 300 mayconsequently be considered to be initialized.

The facility 300 may, based upon its current state, make attempts toreceive the GPS fix 700 at a rate, which may be periodic. In the eventthat the GPS fix 700 cannot be obtained or is invalid, the facility 300may alert a user of the facility 300. In the event that a valid GPS fix700 cannot be obtained during five consecutive attempts, the facility300 may discontinue attempts to get the GPS fix 700, which maynecessitate a manual restart of the facility 300 to renew attempts toobtain the GPS fix 700.

Once obtained or calculated, the location information, which maycomprise the GPS fix 700, may be used in an application serviceincluding, but not limited to, an entertainment application service suchas location-aware games, a commerce application service such aslocation-based transactions, an information application service such asmapping a route from an origin to a destination, or any otherapplication service specified, mentioned, implied, or made apparent bythis discussion.

Referring now to FIG. 9, as mentioned above, the location servicesfacility may support a geofencing application that involves the geofence900. In one case, the geofence 900 is the circumference of a circle thatis defined by a user who specifies a geographic location 902 for itscenter and a radius. In general, the geofence 900 may be defined as anyarbitrary boundary between one geographic area and another, wherein theboundary may be stationary or may move, wherein said movement either maybe correlated to the movement of a physical object such as the portableelectronic facility 300 or may be determined arbitrarily. In any case,the geofencing application may be the alert application and, therefore,may generate the alert when the portable electronic facility 300 crossesthe geofence 900. This alert may be transmitted to the user whospecified the crossing of the geofence 900 as an alert-generating event.Alternatively or additionally, this alert may be transmitted to a seconduser who either opted to receive the alert or who was designated toreceive the alert. Optionally, the alert may pertain to a facility inthe vicinity of the geofence 900, such as and without limitation anadvertisement for a nearby restaurant.

In embodiments, the user may define and/or manipulate a geofence 900 viathe Web browser of the three-tier architecture. Alternatively, the usermay define and/or manipulate a geofence 900 via the portable electronicfacility 300, for example and without limitation via the input facility608 of the portable electronic facility 300.

The location services facility may support a number of end uses. One enduse may comprise a location based adaptable user interface. For example,in an embodiment, the portable electronic facility 300 may be a cellphone. A screen integral to the cell phone may display information tothe user of the cell phone. Under usual circumstances, the screen maydisplay a small menu of options, such as show location and getdirections. However, when the cell phone is within proximity of arestaurant, the screen may display an additional menu option make dinnerreservation. This adaptation to the menu of options is an example of alocation based adaptable user interface.

As is mentioned above, the portableelectronic facility 300 may provide to the user location informationassociated with the portable electronic facility 300, for example andwithout limitation, information in the form of a map. The portableelectronic facility 300 may augment the information provided by thelocation services facility with information from the sensor. Forexample, the location services facility may provide mapping informationto the portable electronic facility 300 according to the location dataprovided by the facility 300 to the location services facility. Uponthis map, the facility 300 may overlay an artificial horizon, whichprovides pitch and roll information to the user. This pitch and rollinformation may be provided to the portable electronic facility 300 bythe sensor.

Yet another end use may comprise outputting location information on theportable electronic facility 300, wherein the location informationitself depends upon the output sensor. For example, in an embodimentwherein the sensor is a visible camera, images of surrounding terrainmay be captured by the camera and may be transmitted to the locationservices facility. The location services facility may analyze theseimages and transmit location information associated with the images backto the portable electronic facility 300. This location information maythen be output by the portable electronic facility 300 for presentationto the user.

More generally, a plurality of end uses may comprise presenting locationbased information to the user in response to the characteristics of alocation. In one embodiment, as described above, the characteristics ofa location may be the terrain in the vicinity of the location. In otherembodiments, the characteristics of a location may, without limitation,comprise the barometric pressure, humidity, temperature, radioactivity,depth, infrared lighting, visible lighting, ultraviolet lighting, and soforth.

Another end use may comprise providing location information associatedwith a transaction. In one embodiment, a person may present a creditcard associated with the user to a merchant at a point of sale. Themerchant or merchant's bank may query the location services facility todetermine the location of the portable electronic facility 300associated with the user. If the portable electronic facility 300 islocated at the merchant then the user may be presumed to be located atthe merchant and the person may be presumed to be the user. Therefore,the transaction may be authorized. Conversely, if the portableelectronic facility 300 is located at a location other than at themerchant then the location of the user may be deemed to be in questionand the person is may not be deemed to be the user. As a result, thetransaction may be denied or the merchant may be required to furtherverify the identity of the user.

Yet another end use may comprise tailoring information to the behaviorof a user. In one embodiment, the location services facility mayrecognize that the route a user usually takes to and from work issuboptimal. In response to this behavior of the user, the locationservices facility may provide to the user a custom tailored,daily-commute route map.

More generally speaking, end uses of the location services facility mayprovide information to the portable electronic facility 300 based oninformation received from the portable electronic facility 300,including but not limited to information associated with the user'sbehavior.

Ageofence around the school can allow a teacher, administrator or parentknow when a child arrives at the school, leaves the school, or the like.Thus, portable electronic facilities 300 can be used to check attendanceagainst the rolls of the school, and to determine the locations ofabsent students who possess such portable electronic facilities 300.

In an embodiment, the tracking 1200 may be associated with health care,such as and without limitation tracking patients, doctors, and/ornurses. In this application, the tracking 1200 may be within a healthcare facility, outside a health care facility, and/or may comprisefinding the closest doctor and/or nurse in an emergency. A geofence maybe established, for example, indicating when a patient has left ahospital, or indicating when a doctor arrives or departs the proximityof the facility, such as to generate an alert if there are not enoughstaff available to handle an emergency.

In another application, the tracking 1200 may be associated with realestate, such as, without limitation, tracking a location of a house forsale, which may be associated with a picture, directions, and/ortracking visitors to the real estate. For example, a portable electronicfacility 300 may be associated with a digital camera, and the locationof a picture or recording, as determined by the tracking facility 1200,may be embedded in the picture or recording for future retrieval of thelocation of the picture. Such a picture or recording location capabilitymay be used to know the location of a real estate location, the locationof an accident, the location where a photo was taken during a vacation,the location of a crime, or the location of another event that isrecorded on the digital camera.

The capability to record the location of a picture or a recording maysupport transport logistics, the adjustment of traffic signals, thedocumentation of potholes, the documentation of defects ininfrastructure, and/or an insurance purpose. The insurance purpose maycomprise documenting the location of accident; capturing a picture orrecording of an accident such as for the purpose of adjusting claims;storing driving habits on file such as for the purpose of determiningsafe driving, which may be associated with changes in insurance pricesbased on driving speed. The picture or recording location tracking maysupport bounty hunters, private investigators, police, detectives, orother in, for example, tracking people. For example, tracking 1200 maysupport tracking a stalker, for example, in determining a distance inrelation to another person where, in some embodiments, an alert that maybe sent to police is sent if the stalker is too close to a person.

In embodiments, the tracking 1200 may support a maid service in, forexample, tracking the time that a maid spends at a location and,perhaps, comparing the actual billed charges to the tracked time.
